- all data lines are in parallel and all scan lines are in parallel, whereas data lines and scan lines are perpendicular to each other. No limitation as such is applied to the present embodiment.
- the array substrate comprises a plurality of RGB sub-pixels lined in parallel with data lines. Each sub-pixel electrically connects its corresponding scan line and data line via a TFT.
- Each pixel area is installed with at least one sub-pixel, and the scan lines forming any two neighboring pixel areas are not the same.

- scan lines 201 and data lines 202 run across but do not touch each other, forming a plurality of pixel areas 203 .
- a plurality of RGB sub-pixels 2031 lines along the data line 202 .
- Sub-pixels 2031 that lined horizontally along a scan line 201 are of the same color.
- Two neighboring sub-pixels 2031 are of opposite polarity. Comparing with conventional technology which arranges sub-pixels along scan lines, the present embodiment requires only one-third of the number of data lines as RGB sub-pixels line along data lines 202 .

- COF chip on film
- scan lines 201 can even installed on the substrate directly without COF. Therefore, RGB sub-pixels 2031 lining along data lines 202 can significantly reduce the cost of the array substrate.
- scan lines 201 forming two neighboring pixel areas 203 are different, meaning that the two neighboring pixel areas 203 lined along the data line 202 do not share a same scan line 201 .
- At least two scan lines 201 are deployed between any two neighboring pixel areas 203 lined along the data line 202 .

- sub-pixels 2031 When sub-pixels 2031 are arranged in arrays, sub-pixels 2031 of the same order number in the neighboring rows connect two neighboring data lines 202 respectively. Neighboring data lines provide different voltages, and when data lines 202 output column inversion data, dot inversion can be realized. The method not only saves the tremendous energy consumed by dot inversion, lowers the cost of the array substrate, and delivers good display effect brought by dot inversion, enhancing display quality.
- the horizontal deployment of scan lines 201 and vertical deployment of data lines 202 are relative.

FIG. 2 for specific description.FIG. 2 is a structure diagram of the array substrate of an embodiment of the present invention. In the present embodiment,scan lines 201 anddata lines 202 run across but do not touch each other, forming a plurality ofpixel areas 203. A plurality of RGB sub-pixels 2031 lines along thedata line 202. Sub-pixels 2031 that lined horizontally along ascan line 201 are of the same color. Two neighboring sub-pixels 2031 are of opposite polarity. Comparing with conventional technology which arranges sub-pixels along scan lines, the present embodiment requires only one-third of the number of data lines as RGB sub-pixels line along data lines 202. Although it means that the number ofscan lines 201 must increase accordingly, chip on film (COF) on the side of thescan lines 201 is a lot cheaper than COF on the side of the data lines 202. In addition, in other embodiments,scan lines 201 can even installed on the substrate directly without COF. Therefore, RGB sub-pixels 2031 lining alongdata lines 202 can significantly reduce the cost of the array substrate. - As shown in
FIG. 2 ,scan lines 201 forming two neighboringpixel areas 203 are different, meaning that the two neighboringpixel areas 203 lined along thedata line 202 do not share asame scan line 201. At least twoscan lines 201 are deployed between any two neighboringpixel areas 203 lined along thedata line 202. The arrangement saves deployment space on the array substrate, reduces non-transparent areas and increases the aperture ratio. - Each
pixel area 203 is installed with two sub-pixels 2031 lined in parallel with a data line. Each sub-pixel 2031 connects itsrespective scan line 201 anddata line 202 via itsrespective TFT 2032. TheTFT 2032 comprises a drain electrically connected to the sub-pixel 2031, a gate electrically connected to thescan line 201, and a source electrically connected to thedata line 202. In a preferred embodiment, each sub-pixel 2031 connects thescan line 201 anddata line 202 that are closest to it. For example, twoscan lines 201 are deployed between two neighboringpixel areas 203 in the present embodiment. The sub-pixels 2031 deployed opposite to each other across the twoscan lines 201 connect the one closest to themselves respectively. In addition, neighboring sub-pixels 2031 lined in parallel with thescan line 201 connectdifferent data lines 202. For example, assume that there are two sub-pixels 2031 lined in parallel with thedata line 202, with data lines arranged horizontally and scan lines vertically, as shown inFIG. 2 . The sub-pixel 2031 on the upper part connects thedata line 202 on the right of thepixel area 203, and the sub-pixel 2031 on the lower part connects thedata line 202 on the left of thepixel area 203. It means that sub-pixels 2031 in odd rows and sub-pixels 2031 in even rows line alternately. When sub-pixels 2031 are arranged in arrays, sub-pixels 2031 of the same order number in the neighboring rows connect two neighboringdata lines 202 respectively. Neighboring data lines provide different voltages, and when data lines 202 output column inversion data, dot inversion can be realized. The method not only saves the tremendous energy consumed by dot inversion, lowers the cost of the array substrate, and delivers good display effect brought by dot inversion, enhancing display quality. - The horizontal deployment of
scan lines 201 and vertical deployment ofdata lines 202 are relative. When the direction of the array substrate changes, the positions ofscan lines 201 anddata lines 202 change accordingly. Therefore, when the position of the array substrate turns 90 degrees or the viewing angle of users turns 90 degrees, the horizontal and vertical deployment switches accordingly. The column inversion becomes a row inversion, but its nature or effect does not change. No limitation as such is imposed here. - Different from conventional technology, a plurality of data lines and a plurality of scan lines of an array substrate of a present embodiment run across but do not touch each other, and form pixel areas. The present embodiment further comprises a plurality of RGB sub-pixels lined in parallel along the data lines. Comparing with the conventional technology with which RGB sub-pixels lined along the scan lines, the present embodiment requires only one-third of the number of data lines, saving the cost of two-thirds of the data lines, and therefore significantly reduces the cost of the array substrate. Each sub-pixel connects to its corresponding scan line and data line through a TFT. Each pixel area is installed with at least one sub-pixel, and the scan lines that form two neighboring pixel areas are different. It means that at least two scan lines are deployed between any two neighboring pixel areas lined along a data line. It saves the layout room on the array substrate, reduces non-transparent areas, and increases aperture ratio. In addition, the two sub-pixels lined in parallel along a data line in each pixel area connect to their corresponding scan lines and data lines via their corresponding TFTs respectively. The two neighboring sub-pixels lined in parallel along a scan line connect to different data lines, with neighboring data lines providing different voltages. When data lines output column inversion data, dot inversion can be realized. It not only saves the tremendous energy consumed by dot inversion, lowers the cost of the array substrate, but also delivers good display effect brought by dot inversion, enhancing display quality.

TheTFT 3032 comprises a drain electrically connected to the sub-pixel 3031, a gate electrically connected to thescan line 301, and a source electrically connected to thedata line 302. In addition, two neighboring sub-pixels 3031 lined in parallel along thescan line 301 connect todifferent scan lines 301.

data line 302 connect to thesame data line 302. Comparing with conventional technology that connects each sub-pixel in a row to a different data line, the present embodiment saves half of the data lines. It means that comparing with conventional technology shown inFIG. 1 , the array substrate of the present embodiment only requires one-sixth of the data lines, saving five-sixths of the data lines and significantly reduces the production cost of the array substrate. - Different from conventional technology, a plurality of data lines and a plurality of scan lines of an array substrate of a present embodiment run across but do not touch each other, and form pixel areas.
